Here's what's happening lately if I slowly in increments of 100rpm from idle raise the rpms somewhere between 900-1100 if held really still the car will stumble and shutdown.

Also when I raise the rpms at idle from the tb adjustment screw to say 1100rpms it's fine for a few seconds then the idle will fluctuate up and down and eveantually stall.

Could it be a faulty tps? I checked it an it seems good voltages are within their specs.

Could it be something dealing with my tec3?

So I set my rpms back at 900rpms and the car is fine no issues. Steady idle oh I also have the USC unplugged because I had issues with it so it's perfect without it. I just want to raise my rpms to 1100 where I feel more at ease with the loads an oil pressures.

 

anyone ?

 

mod list?
